1.安装 Composer

通过 Composer 安装

curl -sS https://getcomposer.org/installer | php mv composer.phar /usr/local/bin/composer

解决方案

sudo vim /etc/php/7.2/cli/php.ini zlib.output_compression = ON

安装成功

2.安装yii2 高级版

安装yii2

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-application

报错：

更换源：

composer config repo.packagist composer https://packagist.phpcomposer.com

报错：

加参数-g global

composer config -g  repo.packagist composer https://packagist.phpcomposer.com

---

再次安装yii2

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-application

更改网络连接方式，桥接方式

安装php-mbstring

sudo apt-get install php-mbstring

报网络连接超时

在浏览器打开安装包地址

不能访问，

发现另外一个复制的虚拟机也打开了，怀疑是IP地址冲突，关掉另外一台虚拟机后，可以打开这个地址

---

再次安装，报错：

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-application

执行：sudo apt-get install phpunitsudo apt-get install php7.2-xml

再次安装，安装成功

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-application

3.配置nginx

sudo vim /etc/nginx/sites-available/default

server {        charset utf-8;        client_max_body_size 128M; listen 80; ## listen for ipv4 #listen [::]:80 default_server ipv6only=on; ## listen for ipv6 server_name frontend.test; root /home/jay/yii-application/frontend/web/; index index.php; access_log /home/jay/yii-application/log/frontend-access.log; error_log /home/jay/yii-application/log/frontend-error.log; location / { # Redirect everything that isn't a real file to index.php try_files $uri $uri/ /index.php$is_args$args; } # uncomment to avoid processing of calls to non-existing static files by Yii #location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ { # try_files $uri =404; #} #error_page 404 /404.html; # deny accessing php files for the /assets directory location ~ ^/assets/.*\.php$ { deny all; } location ~ \.php$ { include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_pass 127.0.0.1:9000; #fastcgi_pass unix:/var/run/php5-fpm.sock; try_files $uri =404; } location ~* /\. { deny all; } } server { charset utf-8; client_max_body_size 128M; listen 80; ## listen for ipv4 #listen [::]:80 default_server ipv6only=on; ## listen for ipv6 server_name backend.test; root /home/jay/yii-application/backend/web/; index index.php; access_log /home/jay/yii-application/log/backend-access.log; error_log /home/jay/yii-application/log/backend-error.log; location / { # Redirect everything that isn't a real file to index.php try_files $uri $uri/ /index.php$is_args$args; } # uncomment to avoid processing of calls to non-existing static files by Yii #location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ { # try_files $uri =404; #} #error_page 404 /404.html; # deny accessing php files for the /assets directory location ~ ^/assets/.*\.php$ { deny all; } location ~ \.php$ { include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_pass 127.0.0.1:9000; #fastcgi_pass unix:/var/run/php5-fpm.sock; try_files $uri =404; } location ~* /\. { deny all;
